Coordinated Turn of Fixed-Wing Aircraft Under Wind Interface on Integral Backstepping

In windy environments, coordinated turning stabilization and high precise of positioning are very vulnerable, and many studies have made it the main goal in their studies. In this article, a new control strategy of stabilizing the fixed-wing aircraft has been introduced in windy environments. First of all, in order to keep the aircraft itself stable, a new type of sliding mode control strategy is applied for control of the attitude and position. Second, we analyze the proposed model in windy environments based on the designed control strategy. Third but the most important, a radial basis function (RBF) network is introduced for decreasing the disturbance error and minimizing the effect of the disturbance. The airplane model has been simulated on many wind conditions in different flying status. We have also applied our control theory to the real flying experiments. From the experiments, it can be clearly found that the proposed method works well in a large range of windy environments and flying status, proposing that our method is effective in the winds.
